Weibull MLEParameter Estimator
Estimates the parameters of the Weibull distribution based on a MLE algorithm. See page 287-288 of Law (2007) Simulation Modeling and Analysis. Uses Newton steps followed by bi-section search (if needed). Convergence is not guaranteed and will be indicated in the EstimatedParameters success property and the message. Requires that the data be strictly positive and that there are at least two observations. Also, requires that all the supplied data are not equal. The user may vary some of the search control parameters to assist with convergence.
Properties
Indicates if the estimator requires that the range of the data be checked for a shift before the estimation process.
Default size of the bi-section search interval around the initial Newton refined estimate. The default is 10.0.
The default number of Newton steps. The default is 10. On average 3.5 steps should provide 4 digit accuracy.
How close we consider a double is to 0.0 to consider it 0.0 Default is 0.001
Desired precision. The default is 0.0001.
Maximum allowed number of iterations. The default is 100
The type of random variable for which this estimator estimates parameters.
Functions
If the estimation process is not successful, then an empty array is returned.
Estimates the parameters associated with some distribution. The returned EstimationResult needs to be consistent with the intent of the desired distribution. Note the meaning of the fields associated with EstimationResult
